Thank you for the gift.
I tried to redeem the product code, but I received a message stating that it has already been activated by a different Steam account and cannot be used again. Could you kindly check with the seller or retailer to see if there might have been a mistake?

The product code you've entered has already been activated by a different Steam account. This code cannot be used again. Please contact the retailer or online seller where the code was purchased for assistance.
